<p>PURPOSE:To obtain a data processing method which enables a high speed processing while holding a calculating accuracy to be high by contriving the calculating method of a fast Fourier transformation(FFT). CONSTITUTION:The first data are inputted as real number part data, and the second data are inputted as imaginary number part data. Then, these two data are simultaneously operated for the calculation of the FFT, the calculated result is divided into the result of the first data and the result of the second data, and the result of the first data and the result of the second data are simultaneously obtained.</p> |
